As long as the “?” shortcut key is not available to international keyboards (ref https://getsatisfaction.com/newsblur/…), please add “h” as an alias.
Making a list of shortcuts available on the keyboard makes me learn shortcuts, which makes me more productive, which makes me more happy 
You can open the keyboard shortcuts dialog by going to Manage > Keyboard Shortcuts.
Yeah.
But if I’m gonna use the mouse, I might as well use the mouse. Having the keyboard shortcuts available as a keyboard shortcut makes keyboard operation much simpler.
And, while I understand that getting the ‘?’ to work might not be all that easy, this one should be quite simple to solve.
I don’t like repeating keys, especially since I plan to use h for a different method one day.
